Core Keywords: aluminum discs, aluminum circles, 1060 aluminum discs, 3003 aluminum discs, hardware processing aluminum blanks, deep draw aluminum discs
Aluminum discs (also called aluminum circles) are core raw blanks for hardware processing, widely used in kitchen utensils, daily hardware, decorative hardware, and industrial hardware accessories. 1xxx series pure aluminum discs and 3xxx series anti-rust aluminum discs are the two most popular materials in hardware manufacturing, with different properties matching different processing techniques and end-use requirements. Mastering specification customization and material selection skills helps hardware enterprises improve product qualification rates, reduce production costs, and meet performance targets.
Ⅰ. Performance Differences Between 1xxx & 3xxx Series Aluminum Discs
- 1xxx Series (1060) Pure Aluminum Discs: High-purity blanks with ultra-high ductility and softness, perfect for deep drawing, stretching, and polishing. Low cost, basic corrosion resistance, ideal for mass-produced general hardware products
- 3xxx Series (3003) Aluminum-Manganese Alloy Discs: Higher strength and hardness than pure aluminum, better rust and wear resistance, suitable for load-bearing and outdoor hardware. Slightly lower ductility but higher overall durability
Ⅱ. Core Specification Customization Items for Aluminum Discs
Aluminum disc customization focuses on four key parameters, tailored to hardware processing technology and final product size:
- Diameter: Conventional range 50mm-1000mm, precision custom sizes available for special products
- Thickness: Mainstream range 0.3mm-6.0mm (thin gauge for small decorative hardware, thick gauge for large load-bearing accessories)
- Temper: O temper for high-stretching applications; H12/H14 temper for hard, shape-retaining products
- Surface Finish: Mill finish, polished, or passivated, selected based on final product surface requirements
Ⅲ. Material Selection Skills for Different Hardware Processing Scenarios
- Kitchen & Daily Hardware (Deep Drawing Needs): Choose 1060 O temper pure aluminum discs (no cracking during stretching, easy polishing, cost-effective for mass production) for aluminum pots, bowls, ladles, and daily utensils
- Industrial & Outdoor Hardware: Choose 3003 H14 temper aluminum discs for high hardness and corrosion resistance, suitable for lamp bases, pipeline accessories, outdoor tool parts, and decorative hardware
- Precision Small Hardware: Thin-gauge 1xxx series aluminum discs to cut material costs; Large load-bearing hardware: Thick-gauge 3xxx series aluminum discs for structural strength
Ⅳ. Processing Quality Control Tips for Aluminum Discs
- Select aluminum discs with uniform thickness and no eccentricity to avoid uneven stretching
- Choose blanks with smooth surface, no scratches, cracks, or oxide layers for high-quality finished products
- Confirm matching temper: Over-hard temper causes stretching cracks; over-soft temper leads to product deformation
- Match customized specifications strictly to processing molds to reduce material waste
